4. Peritoneal dialysis

It is a dialysis modality that utilizes the peritoneal cavity as a dialyzing space. Hemodialysis, continuous renal replacement therapy, and intermittent hemofiltration involve different mechanisms for solute and fluid removal.

wer: C
anation: Acute tubular necrosis (ATN) is the most common cause of a ey injury (AKI) in hospitalized patients. It is characterized by the uction of renal tubular cells, often due to ischemia or nephrotoxic age
options such as glomerulonephritis, renal artery stenosis, and rolithiasis may cause kidney injury, but they are not the most commo es in the hospital setting.

Explanation: Hemorrhage, or excessive bleeding, is a potential complication of heparin use during hemodialysis. Heparin is often used as an anticoagulant during the procedure to prevent clotting within the dialysis circuit. Hyperkalemia (high levels of potassium), hypoglycemia (low blood sugar), and hypercalcemia (high levels of calcium) are not directly associated with heparin use.
Question: 8
Which of the following is a potential complication of long-term hemodialysis?
1. Diabetic ketoacidosis
2. Thyroid storm
3. Gout
wer: D
anation: Amyloidosis is a potential complication of long-term odialysis. It occurs due to the accumulation of amyloid proteins in var ns and tissues, leading to organ dysfunction. Gout is a form of arthriti ed by the deposition of uric acid crystals in joints and is not directly r modialysis. Thyroid storm and diabetic ketoacidosis are complication oid dysfunction and diabetes, respectively, and are not specifically ciated with hemodialysis.

Answer: C
Explanation: Epoetin alfa is a medication commonly used to treat anemia in
hemodialysis patients. It is a synthetic form of erythropoietin, a hormone that stimulates the production of red blood cells. Lisinopril is an angiotensin- converting enzyme (ACE) inhibitor used to treat hypertension, not anemia. Metformin is an oral antidiabetic medication, and warfarin is an anticoagulant.
